Hi again,<br>a side note:<br>in the subject of your email, you are asking for "supporting ECW as a plugin" whilst in the body of your email you are generally asking for supporting ECW in GDAL.<br>The steps I have suggested in the previous email, are needed only if you need to add ECW support as a separate plugin.<br>
In case your aim is simply adding ECW in GDAL (without leveraging on the "Plugin way") you can simply rebuild GDAL after having removed the "ECW_PLUGIN = YES" line from NMAKE.opt. <br><br>Hope this help.<br>

Hi, <br>I did a similar thing on 1.4.4 and 1.5.3.<br>Basically, you are building ECW driver as a plugin as stated by the flag ECW_PLUGIN = YES<br>Therefore, you need to do a separate build of the ECW GDAL Driver. <br>Go in gdal/frmts/ecw and run "nmake /f <a href="http://makefile.vc" target="_blank">makefile.vc</a> plugin"<br>
This command should produce a gdal_ECW_JP2ECW.DLL.<br><br>Finally you need to define a GDAL_DRIVER_PATH environment variable linking to the location where you have built gdal_ECW_JP2ECW.DLL.<br>After this, gdalinfo should find the ECW driver.<br>
<br>Let me know if you have additional issues, since I did these steps on 1.4.4 which needed some fixes that I have copied from 1.6.0 code. (I guess 1.6.0 already contains all the proper declarations)<br><br>Regards,<br>

Hello , I have some question about supporting ECW in gdal.but I can not<br>
solve it. My step is following:<br>
<br>
1.I download gdal-1.6.0 and<br>
ImageCompressionSDKSourceCode3.3Setup_20070509.zip from ERMaper webset and<br>
Windows Server 2003 R2 Platform SDK from microsoft website.<br>
2. I set up Windows Server 2003 R2 Platform SDK on my computer in D:\Program<br>
Files2.<br>
3. I unzip the ImageCompressionSDKSourceCode3.3Setup_20070509.zip,and select<br>
E:\libecwj2-3.3<br>
\Source\NCSBuildQmake\libecwj2_win32_net_shared.vcproj,using visual<br>
studio 2005.When open the file,<br>
it needs translate, and it translates well with no error and just two<br>
warnings.<br>
4. I set visual studio 2005 project->c/c++->general ->include directory,and<br>
add D:\Program Files2\Microsoft Platform SDK for Windows Server 2003<br>
R2\Include<br>
5. I select debug,win32 ,and build libecwj2.dll successfully,and it is<br>
included in E:\libecwj2-3.3\Source\NCSBuildQmake\Debug<br>
6. I unzip gdal-1.6.0 to E:\gdal-1.6.0. change MSVC_VER=1400 .<br>
7. for ECW support, I Uncomment the following and update to enable ECW<br>
support.<br>
# Uncomment the following and update to enable ECW support.<br>
ECW_PLUGIN = YES<br>
ECWDIR = E:\libecwj2-3.3<br>
ECWLIB = $(ECWDIR)\Source\NCSBuildQmake\Debug\libecwj2.lib<br>
8. open E:\gdal-1.6.0\frmts\leveller\levellerdataset.cpp,and change { "?,<br>
kPI / 180.0, UNITLABEL_DEGREE } to<br>
{ "?", kPI / 180.0, UNITLABEL_DEGREE }<br>
9. I start visual studio 2005 commandline , and change the path to<br>
E:\gdal-1.6.0, then ,I inputs command nmake /f <a href="http://makefile.vc" target="_blank">makefile.vc</a>,nmake /f<br>
<a href="http://makefile.vc" target="_blank">makefile.vc</a> install and nmake /f <a href="http://makefile.vc" target="_blank">makefile.vc</a> devinstall.<br>
10. I copy gdal16.dll to C:\WINDOWS\system32.<br>
11. I set tools->options->projec and solution -> vc++ direction<br>
->includingfile->C:\warmerda\bld\include<br>
<br>
->libraries->C:\warmerda\bld\lib<br>
12.I build a new project,and code following:<br>
#include "gdal_priv.h"<br>
#include "stdio.h"<br>
#include "gdal.h"<br>
#pragma comment(lib, "gdal_i.lib")<br>
int main()<br>
{<br>
const char *p=NULL;<br>
GDALDataset *poDataset=NULL;<br>
GDALDriver *pDriver=NULL;<br>
GDALAllRegister();<br>
int t =GDALGetDriverCount();<br>
printf("%d\n",t);<br>
for(int k=0;k<t;k++)<br>
{<br>
const char *pt=NULL;<br>
pDriver=(GDALDriver *)GDALGetDriver(k);<br>
pt=pDriver->GetDescription();<br>
printf("%s\n",pt);<br>
}<br>
}<br>
result:<br>
